* Adjusting upstart job so restarting squid-deb-proxy does not result
in killing squid-deb-proxy-avahi. (LP: #677276)
* Also adjusting upstart job so squid-deb-proxy does not get started
a real network interface is up and all local filesystems are mounted

* debian/squid-deb-proxy.squid-deb-proxy-avahi.upstart:
- start only once avahi-daemon is available (thanks to dholbach)
* debian/control:
- add dependency on apt for squid-deb-proxy-client
(thanks to dholbach)
